+Notmuch 0.18 (UNRELEASED)
+=========================
+
+Command-Line Interface
+----------------------
+
+`notmuch dump` now defaults to `batch-tag` format
+
+ The old format is still available with `--format=sup`.
+
+`notmuch new` has a --quiet option
+
+ This option suppresses the progress and summary reports.
+
+Emacs Interface
+---------------
+
+Init file
+
+ If the file pointed by new variable `notmuch-init-file` (typically
+ `~/.emacs.d/notmuch-config.el`) exists, it is loaded at the end of
+ `notmuch.el`. Users can put their personal notmuch emacs lisp based
+ configuration/customization items there instead of filling
+ `~/.emacs` with these.
+
+Changed format for saved searches
+
+ The format for `notmuch-saved-searches` has changed, but old style
+ saved searches are still supported. The new style means that a saved
+ search can store the desired sort order for the search, and it can
+ store a separate query to use for generating the count notmuch
+ shows.
+
+ The variable is fully customizable and any configuration done
+ through customize should *just work*, with the additional options
+ mentioned above. For manual customization see the documentation for
+ `notmuch-saved-searches`.
+
+ IMPORTANT: a new style notmuch-saved-searches variable will break
+ previous versions of notmuch-emacs (even search will not work); to
+ fix remove the customization for notmuch-saved-searches.
+
+ If you have a custom saved search sort function (not unsorted or
+ alphabetical) then the sort function will need to be
+ modified. Replacing (car saved-search) by (notmuch-saved-search-get
+ saved-search :name) and (cdr saved-search) by
+ (notmuch-saved-search-get saved-search :query) should be sufficient.
+
+The keys of `notmuch-tag-formats` are now regexps
+
+ Previously, the keys were literal strings. Customized settings of
+ `notmuch-tag-formats` will continue to work as before unless tags
+ contain regexp special characters like `.` or `*`.
+
+Changed tags are now shown in the buffer
+
+ Previously tag changes made in a buffer were shown immediately. In
+ some cases (particularly automatic tag changes like marking read)
+ this made it hard to see what had happened (e.g., whether the
+ message had been unread).
+
+ The changes are now shown explicitly in the buffer: by default
+ deleted tags are displayed with red strike-through and added tags
+ are displayed underlined in green (inverse video is used for deleted
+ tags if the terminal does not support strike-through).
+
+ The variables `notmuch-tag-deleted-formats` and
+ `notmuch-tag-added-formats`, which have the same syntax as
+ `notmuch-tag-formats`, allow this to be customized.
+
+ Setting `notmuch-tag-deleted-formats` to `'((".*" nil))` and
+ `notmuch-tag-added-formats` to `'((".*" tag))` will give the old
+ behavior of hiding deleted tags and showing added tags identically
+ to tags already present.
